Former Miss Wales and Beauty queen Sophia Cahill choked back tears as she told how Gough shoved her into the passenger door of his white VW campervan. She said she was "shocked and upset" after the attack, which happened when Gough arrived more than an hour late for a meeting at her home on the evening January 5 this year.
Giving evidence from behind a blue curtain, Miss Cahill had told the court: "I opened the passenger door and Ian just stormed around the front of the van. He had the front of my shoulder and he just flung me back."
Chairman of the bench Terry Carpenter told Croydon Magistrates Court the magistrates had found the evidence of Miss Cahill was "convincing" and backed up by Mr Bowers.
